PROBLEM TO BE SOLVED: To provide a holding method capable of holding garden stuff safely, while showing an extremely high freshness retention effect, even in a storage chamber such as a container having a volume of 1 mor having a large volume exceeding 10 m, concerning a novel holding method of garden stuff.SOLUTION: When storing and holding garden stuff 2 in a storage chamber 1 such as a container, a packed bed 3 by the garden stuff is formed, and process gas having a hydrogen concentration of 0.1-4.0 vol% is allowed to pass from one side of the storage chamber toward the other side through the packed bed 3 so that a space velocity (SV) becomes 0.1 cm/sec-100 cm/sec.SELECTED DRAWING: Figure 1【課題】 青果物の新規な保存方法に関し、容積が１ｍ３、更には、１０ｍ３を超えるような大容積のコンテナのような保管室においても、極めて高い鮮度保持効果を発揮しながら、安全に青果物の保存を行うことを可能とした保存方法を提供する。【解決手段】 青果物２を、コンテナ等の保管室１に収容して保存するに際し、上記青果物による充填層３を形成し、該充填層３を介して保管室の一方から他方に向けて、空間速度（ＳＶ）が０．１ｃｍ／秒～１００ｃｍ／秒となるように、水素濃度が０．１～４．０容量％の処理ガスを通過せしめる。【選択図】 図１
